Y fingers and it is desirable to incorporate some Y sort of wear resistant material at this portion of the glovein order to prolong its life. When gloves become wet they become more or less slippery and it is diiiicult to hold articles with them. Consequently, it is desirable to modify the surface of the glove so as to Iimprove its gripping qualities.

It is an obj ect of this lnvention to provide a 'glove bearing a reinforcement of rubber composition. Another object is to provide a glove reinforced with a sheet of yrubber having cup-like depressions 'in the surface thereof For a complete disclosure of the nature and objects vof the invention, reference is had to the accompanying specification and drawings, in which latter:

Fig. 1 is a front elevation of a glove showing the reenforcement;

Fig. 2 is a transverse sect-ion along the line 4 2--2 of Fig. 1; 4

Fig. 3 is a cross section of a modified form l of glove; and

Fig. 4 1s a cross section of an additional modified form of glove.

In carrying out the invention in its preferred form, crepe rubber is prepared in the following way:

A mass of rubber is compounded on a mill with such curativeagents and fillers, as may be desired, a suitable composition comprising: y

Parts by weight Rubber 100 Zinc oxide` l@ Sulphur 2 Zinc dimethylamine dithiocarbamate 1A), This compound is sheeted in the form of crepe rubber to' the desired thickness. The term crepe rubber is used in its usual significance and shape of the palm, fingers and thumb.

of the glove. It is aiixed to the corresponding blank 2 of fabric by a layer of rubber cement, a suitable composition for which is rubber 10 parts by weight and benzol 90 parts by weight. The cement is applied to the fabric after which the crepe rubber sheet is secured in place with or without the use of pressure. To further secure the crepe, the edges of the two are stitched together with thread 3. The blanks are then fabricated into the form of a glove which can now be used as a completed article, a cross section of which is shown in Fig. 2, or'it can be vulcanized by heating the same for approximately one hour at 220 F. Under some circumstances it may be desirable to vulcanize under pressure.

It may be desirable to formulate a waterproof glove such as is illustrated in cross is sprayed or dipped or both Witha dispersion of rubber composition. A suitable composition comprises:

, Ps1-mty weight Dry rubber (as semi-'cured latex containing 40% solids) 100 Zinc oxide 60 Lithopone 40 Ultramarine blue 1/8 Glue 20 Sulphonated castor oil 5 Sulphur v 2 Zinc dimethylamine dithiocarbamatel@ Sodium silicate 1 Nujol emulsion 25 Nekal 2 Sodium resinate' 11/2 This composition forms a dispersion of rubber in water containing about 55% of solids. If any or all of the rubber composition is to be applied to the glove bys raying, it is desirable to dilute the same wit sutliclent water t'o form a com osition'containing approximately so `ds. The zinc oxide, lithopone and ultramarine blue fimction as colorlng agents. J The glue and the sodium silicate actas stabilizers. The sulphonated castor oil gives a smooth surface to the rubber coating. The nekal functions as both a stabilizer-and a thinning agent, while-the sodium resinate serves as. a thinning agent.

Thenujol actsas asofteningV agent. The sodium resinate aids in incorporating the emulsion into the disersion. The glue as.-

composition encasing the entire glove.

1s aixed in place over the cement.

scribed, hasa rough non-slip As an alternative, a glove, such as has been illustrated in Fig. 4, can be manufactured.

In so doing, a fabric glove is Afabricated in the usual manner, after which it is'dipped in a dispersion of rubber of a com os1t-1on similar to that previously disclose after which it is dried and a layer. of rubber cement is applied to the palm, fingers and thumb of the glove. A sheet of crepe rubber com osition ulcanization of .the assembled arts results in a glove having a base 2 of fbric', a coating of rubber composition 4 and a reinforcement of crepe rubber 1 uponv the surface.

While theinvention has been described as I Iclaim and It will be understood that the love pi eavy wor such as in handling brick, cement, machinery, etc. When the glove is entirely coated with rubber com osition, it, is

suitable for use around acid p ants. When made only of fabric with the crepe palm, the glove presents a water proof surface to the article to be gripped and at the same time permits ventilation of the hand through the back of the glove.

Having thus described my invention, what desire to protect by Letters Patent is: i

1. A glove com rising hand and wrist portions made of fabric exteriorly coated with waterproofing composition, and a layer of vulcanized crepe rubber fixed to and covering the palm and front portions of the fingers and thumb. I

rticularly adapted for rough` 2. A glove of fabric coated with thinV vlayer of vulcanized rubber composition, and a lalyifer of vulcanized crepe rubber relatively thic as compared to the other layers of the article coverlng the p'alm andlface portions of the lingers and thumb iof'the glove.

' 3. A glove of fabricqoated with a" thin layer of vulcanized rubber composition, and a layer of vulcanized crepe rubber relativelyr thick as compared to the other layers of the article covering the palm and face portions of the fingers and thumb of the'glove, said crepe rubber being united to the thln layer of rubber composition b vulcanization.l
